Summaries for IMPA2 Gene

Entrez Gene Summary for IMPA2 Gene

  • This locus encodes an inositol monophosphatase. The encoded protein catalyzes the dephosphoylration of inositol monophosphate and plays an important role in phosphatidylinositol signaling. This locus may be associated with susceptibility to bipolar disorder. [provided by RefSeq, Jan 2011]

GeneCards Summary for IMPA2 Gene

IMPA2 (Inositol(Myo)-1(Or 4)-Monophosphatase 2) is a Protein Coding gene. Diseases associated with IMPA2 include bipolar disorder and schizophrenia. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include protein homodimerization activity and inositol monophosphate 3-phosphatase activity. An important paralog of this gene is IMPA1.

UniProtKB/Swiss-Prot for IMPA2 Gene

  • Can use myo-inositol monophosphates, scylloinositol 1,4-diphosphate, glucose-1-phosphate, beta-glycerophosphate, and 2-AMP as substrates. Has been implicated as the pharmacological target for lithium Li(+) action in brain.
